KNOCKDOWN METAL SHIPPING CASE.

Application filed July 19,

To all w from it may concern:

Be it known that I, Yi ILLiAM HARTLEY, a subject of the King of Great Britain, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Knockdown Metal Shipping Cases; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, 111- Fig. 1, a top or plan view of a knock-down metal shipping case constructed in accordance with my invention.

This invention relates to an improvement in knock down metal shipping cases, adapted to be made in a variety of sizes, being adapted for very small boxes as well. as the larger sizes, such as used in packing drygoods. It has long been recognized that a great waste occurs by the use of shipping goods in wooden cases. it has also been recognized that it is desirable that packing cases should be capable of being knocked down for the purpose of returning them to the original shipper.

The object of this invention is to provide a knock down box which may be struck up from sheet-metal, which will have corresponding parts, so as to be interchangeable.

it may be readily set up, firmly united together and easily knocked down and confined in a knocked down position, and the invention consists in the construction and arrangement of parts as will be hereinafter described and particularly recited in the claims.

In carrying out my invention the top 20 and bottom 21 correspond in size and shape, each having a flange 22 at each side turned at right-angle to plane of the top or bottom. These members are also formed with longitudinal ribs 23 shorter than the length of the top and bottom and open at their ends ,for the purpose as hereinafter appears. The sides 24 and 25, correspond to each other and have inwardly turned edges 26. These sides are preferably formed with vertical ribs 27 for the purpose of strengthening. The ends 28 are formed with outwardly turned edges 29 and preferably formed with corrugations 30 and near the edges, perforations 31 are arranged in line with the ribs 23 in the top and bottom. The sides are interlocked with the ends and the four parts set into the bottom and staples or U shaped strips 32 are inserted through the perforations 31 in the ends, through holes formed for them through the edges of the top and through the ribs 23 which are arranged in pairs.

After the case is filled the top is set in place and this is also secured in place by staples or U shape bars 32 and the ends of these bars may be bent down or connected together by a seal lock. If desired and as shown the central portion 33 of the top and bottom members may be slightly deeper than the remain ing portions. When the staples are removed the parts may be readily knocked down and by placing the sides and ends between the tops and bottom, they are adapted to be connected together by the staples 32. In this case, however, one leg of the staple passes through the top and the other through the bottom, as clearly shown in Fig. 5.

These boxes may be lined with sheets of asbestos or other fire-proof material, with water-proof material or with heavy felt, thus producing a box that may be fire-proof, Water-proof or suitable for packing goods which might otherwise be injured in shiping. It can be seen that I produce at very ow cost, and in simple manner, a shipping case, which may be securely fastened, easily knocked down and the parts when knocked down secured together for safety in re-shipping.

I claim:

- 1. A knocked down box comprising sides, and ends adapted to be interlocked there with, and a bottom and a top adapted to interlock with said sides andends, saidtop and bottom each formed with longitudinal openended ribs which are shorter than the length of the top and bottom, so as to be located be: tween the ends thereof, combined with fastening means adapted to pass through the said ends and through the ribs in the top and bottom, a

2. A metal shipping-case comprising sides, and ends transversely corrugated and adapted to be interlocked at their edges, a top and a bottom each formed with open-ended longibottom, and combined with fastening means adapted to pass through the perforations in the top and bottom and endsand through the said ribs.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
